Swiss company Borobotics has unveiled a technological breakthrough with its autonomous drilling machine called Grabowski . Designed to facilitate access to geothermal energy in urban spaces, this innovation promises to transform the sustainable energy sector .
Grabowski is a compact and efficient drilling machine
Measuring just 2.5 metres long and 135 millimetres in diameter, this machine is positioned as a lightweight alternative to traditional drilling machines that require large surfaces. Its ability to operate in tight spaces, such as gardens or garages, makes it ideal for urban environments. In addition, its operation requires a space of between 6 and 8 m², allowing drilling in places previously considered unfeasible.
Equipped with advanced sensors, the Grabowski “robotic worm” works autonomously. It is able to detect the different layers of the ground, adapting to the conditions of the earth and ensuring a straight path during drilling . In case of encountering obstructions such as water or gas, it seals the well to ensure safety. This technology also allows for quick installation by a single worker, who can monitor multiple sites at the same time.
Benefits of robotic worm
One of the main advantages of Grabowski is its environmental friendliness. Unlike traditional drilling rigs that consume large amounts of diesel , this robot operates exclusively on electricity . This translates into an 86% reduction in CO₂ emissions per hole drilled. In addition, its low noise level, less than 60 dB, minimises disturbance in residential environments.
With a drilling capacity of up to 500 metres, the worm targets shallow geothermal energy, ideal for sustainable heating and cooling systems . Borobotics has already started developing a waiting list for interested customers, anticipating the installation of heat pumps in mid-2025. This development not only promises to reduce energy costs, but also accelerate the transition to a decarbonised economy.
